Statistically speaking though, there are way more people on Head-Fi who own LCD2s than HE500s. Just look at the difference:
http://www.head-fi.org/products/hifiman-he-500 (76 people own it)
http://www.head-fi.org/products/audeze-lcd2-planar-magnetic-headphones (307 people own it, and there's also 17 more who own LCD2r2 which is a separate category)
So the bias should theoretically be on LCD2s rather than HE500s, and yet the polls are the other way around.
Which means HE500s win
(Joking of course, so many variables are not being controlled for with these simplistic forum polls, they don't mean sht)
